McCalliog scored in the famous 3-2 win over world champions England at Wembley in 1967, 50 years ago this weekend.
It was a debut to remember for McCalliog, who was taken with the bow of Stuart Armstrong in last month's 1-0 World Cup qualifying win over Slovenia.
"I was very pleased for Gordon and for the boys because it was a real pressure situation," said McCalliog.
"I was actually at the game, I thoroughly enjoyed it. They put a smile back on Scottish soccer that night."
Strachan had commented that Armstrong's man-of-the-match performance at Hampden was the best Scotland debut he had ever seen.
McCalliog, just 20 years old at the time, scored with three minutes remaining as Scotland recorded arguably their most distinguished victory, with Denis Law and Bobby Lennox also on target.
"With regards to the comparison (with Armstrong) I think that's what football is all about," McCalliog told BBC Scotland's Sportsound. "We all have opinions and that's what keeps the game bubbling along."
McCalliog, who had spells at Chelsea, Sheffield Wednesday, Wolves and Manchester United, would only win another four Scotland caps after netting the third goal in the Wembley win.
However, he says he has no regrets and simply cherishes the appearances he did make and having the chance to be part of the triumph over the World Cup holders.
"It seems like yesterday," he said. "It's a wonderful memory and it's still imprinted very much so in my head, it was a fabulous day.
"People would save up for two years so they could go to Wembley. It was an important game, we had it rammed down our throat about 1966 so all the boys were determined we would get a good result.
"To have Billy Bremner on my right-hand side and the wonderful James Baxter on my left was a dream come true.
"There were easily four world class players in the England side; Bobby Moore, Bobby Charlton, Alan Ball and probably Ray Wilson and that's not to mention Gordon Banks. They certainly were a great side, they were unbeaten for 18 games, and it was a tough call for us to go out and beat them.
"The Scotland selection was quite difficult back then. The manager didn't pick the team, the committee did. There was a lot of competition. I'm very grateful for the five caps, it would have been nice to have got a few more."
Manager Gordon Strachan has "put a smile back on Scottish soccer", says former Scotland hero Jim McCalliog.

The charges include robbery, grievous bodily harm and possession of an item to discharge a noxious substance.
The five attacks took place in 90 minutes across north and east London.
The 16-year-old has been remanded in custody to appear at Stratford Youth Court on Monday. A 15-year-old boy also arrested has been released on bail.
The 16-year-old has been charged with:
Police said the investigation into the five separate attacks "remains ongoing".
Speaking before the boy was charged Ch Insp Ben Clark, from the Met's Hackney Borough, said all of the victims had been riding mopeds.
One victim suffered "life-changing injuries".
Jabed Hussain, 32, was one of the five people attacked on Thursday and said his helmet saved him from worse injury.
"I took off my helmet and I was just screaming for help because it's getting dry and as much as it's getting dry it's burning. So I was just screaming for water," Mr Hussain said.
A 16-year-old boy who was arrested in connection with five acid attacks in London on Thursday has been charged with 15 offences, police have said.

It happened outside a supermarket at Coleraine Road in Portstewart on Wednesday afternoon.
Her mother's car keys had fallen inside the vehicle, and when the door was closed, the security system activated the locks.
The fire crew managed to gain entry to the car and bring the baby out.
Mark Smith of the Fire and Rescue Service said: "We were able to release the door - and we're delighted to have been able to reunite the baby with her mother."

Firefighters have rescued a seven-week-old baby who was accidentally trapped inside her mother's car in County Londonderry.
